Advancing device in electrically driven typewriters and similar machines

In an advancing device for the motorized vertical forward or reverse movement of a record carrier in an electrically driven office machine, which device includes an operating element mounted for displacement in either one of two directions from a zero position, and means responsive to displacement of the operating element in a first one of the two directions for effecting forward vertical movement of such carrier and responsive to displacement of the operating element in the second one of the two directions for effecting reverse vertical movement of such carrier, the improvement wherein said means are responsive to displacement of said operating element in the first direction to at least three successive distances from the zero position for moving the record carrier at a rate which increases between at least three values which increase successively from one value to the next as the extent of displacement of said operating element from the zero position increases from one successive distance to the next, with each successive distance being associated with a respective one of the three rate values.
